In February 2013, Curiosity drilled into a rock called "John Klein" and then analyzed the sample material with its on-board scientific instruments. On March 12, NASA announced that the analyses show conditions on Mars were once favorable for life! Join us to learn more about this breakthrough discovery.

Tardigrades are amazing creatures that can withstand the most extreme conditions on Earth, as well as the vacuum of space! This unique and charismatic animal has the ability to survive in a variety of situations. In today's program, Exploratorium scientist Karen Kalumuck will continue our programming about life in extreme environments as it relates to the search for 'habitability' on Mars.

In today's program, Exploratorium scientists Paul Doherty and Karen Kalumuck will look at examples of life in extreme environments on Earth. As Mars is an extreme environment, the question remains-could it have supported any form of microbial life?

Why is water, or evidence of water, so important to the Mars missions?
Join Exploratorium scientists Ron Hipschman and Karen Kalumuck as they examine water as one of the building blocks for life and what previous Mars missions have discovered about water on the red planet.

Virtual worlds have physics. In this exhibit a visitor knocks over a small domino which knocks over a larger domino and so on down an exponentially growing line of dominoes which all the while obey the laws of physics.

This After Dark, the Exploratorium hit repeat on favorite memories. Guests explored the fascinating worlds of reminiscence and repetition—and then backwards skated through their own nostalgia on our temporary roller rink.

You've probably heard about the Texas-sized island of plastic trash swirling in the center of the Pacific Ocean. But did you know we have our own pockets of floating trash right here in San Francisco Bay? Join us on a trash safari with Sealife Convervation—a research and education group studying the volume, distribution, and sources of trash in the San Francisco and Monterey Bays.

Made by the Exploratorium's Teacher Institute, this "machinima"--a film made entirely in a virtual world, highlights the exhibits and recent events in Second Life on the Exploratorium Island and 'Sploland sims.
